UP/DOWN
Input for setting a zero point anywhere
within the programmed encoder resolution.
The zero setting operation is triggered by a
High impulse and has to be in line with the
selected direction of rotation (UP/DOWN).
Connect to GND after setting operation for
maximum interference immunity. Impulse
duration >100 ms.

Diagnostic output.
An error warning is given at level Low.
Important: Interferences must be drained
by the downstram electronics.

Please use cores twisted in pairs (for
example clock+ / clock-) for extension cables of more than 10 m length.

Trigger level
UP/DOWN counting direction input.
This input is standard on High. UP/DOWN
means ascending output data with clockwise shaft rotation when looking at flange.
UP/DOWN-Low means ascending values
with counterclockwise shaft rotation when
looking at flange.
